After 12 years, a deposit of $10,000 into your college account has earned $6,000 in interest payments. What simple interest rate did the account earn
Answer:
5%
Step-by-step explanation:
I = PRT/100 where I = interest, P = initial deposit, R = the rate in %, T = number of years.
So substituting the given values:
6000 = 10000*R* 12/100
10000*12*R = 100*6000
R = 100*6000 / (10000 * 12)
R = 600000/120000
= 5%

The Crazy 80s Baby Jr. Decides to make a Crazy Cake for dessert. The cake uses eggs and potatoes in a ratio of 2:5. If she uses 6 eggs, how many potatoes will she need?
Answer:
When
eggs = 6, Potatoes = 15
Step-by-step explanation:
Ratio of egg to potatoes
Egg : potatoes
2 : 5
If she uses 6 eggs, how many potatoes will she need?
Eggs = 6
Potatoes = x
2 : 5 = 6 : x
2 / 5 = 6 / x
Cross product
2 * x = 5 * 6
2x = 30
x = 30 / 2
x = 15
When
eggs = 6, Potatoes = 15

Michael chose some positive number, multiplied it by itself, added 1, multiplied the result by 10, added 3, and multiplied the result by 4. His final answer was 2012. What number did Michael choose?
Answer: 7
Step-by-step explanation:
Let the number chosen by Michael be x.
We are told that he multiplied it by itself, added 1. This would be:
= = ( x × x) + 1 = x² + 1
We are further told that he multiplied the result by 10, and added 3. This would be:
= = [(x² + 1) × 10] + 3
= 10x² + 10 + 3
= 10x² + 13
Lastly, he multiplied the result by 4 and his final answer was 2012. This would be:
(10x² + 13) × 4 = 2012
40x² + 52 = 2012
40x² = 2012 - 52
40x² = 1960
x² = 1960/40
x² = 49
x = ✓49
x = 7
The number is 7
can be expressed as:
= ( x × x) + 1 = x² + 1

Answer:
y = [tex]\frac{1}{2}[/tex] x + 4
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, 8) and (x₂, y₂ ) = (10, 9)
m = [tex]\frac{9-8}{10-8}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 8) , then
8 = 4 + c ⇒ c = 8 - 4 = 4
y = [tex]\frac{1}{2}[/tex] x + 4 ← equation of line

Answer:
2x + 7y and 7g + 3h
Step-by-step explanation:
(a)
3x + 5y - x + 2y ← collect like terms
= (3x - x) + (5y + 2y)
= 2x + 7y
(b)
3g + 5h + 4g - 2h ← collect like terms
= (3g + 4g) + (5h - 2h)
= 7g + 3h
Answer:
A) 2x + 7y
B) 7g + 3h
Step-by-step explanation:
A) 3x + 5y - x +2y =
3x - x = 2x
5y + 2y = 7y ans: 2x + 7y
B) 3g + 5h +4g - 2h =
3g + 4g = 7g
5h - 2h = 3h ans: 7g + 3h

Is the Point on the Line?
Answer:
yes.
Step-by-step explanation:
The eqation of the line is y=1/2x+3 so when we plug in x as 20 y is equal to 13
Answer:
Yes it is on the line becuase if you find the slope of the line which is 1/2. We can just use rise over run from there. So we know 1 is y and 2 is x Becuase slope is written in y/x. And we can fins slope by just calculating the rise over run or suing the formula y2-y1/x2-x1. So the last pont shown on the line is (10,8) so we can add 1 to the y or in this case 8 and add 2 to the x or in this case 10. You’ll get (12,9). We know this works becuase if you find the slope of (12,9) and (10, 8), you’ll get 1/2 again which is the same slope so we know it’s right. Now we just add using the same slope to the now new point. We add 1 to 9 and add 2 to 12. (14,10). Still, if you find the slope, it’ll still be 1/2. Now keep repeating that and you’ll get (20, 13) eventually. And we can check by calculating the slope. (20,13) and (10,8), you could use any point on the coordinate plane/ and you’ll get 1/2. A easier way could just be calculating the slope first and you’ll get 1/2 from any two points and then use any two points to calculate the slope for (20,13). It’ll still be the same thing.

15 - (-5) =
Answer: 20
===========================================
Explanation:
The two negatives cancel to form a positive. A negative is just opposite. So we have two opposites canceling.
15 - (-5) = 15 + 5 = 20

Here's another way to look at it:
Let's say we're on the 15th floor of a skyscraper. We can think of each floor of the skyscraper as part of a vertical number line (or ruler).
If we go up 5 floors, then we write 15+5 = 20 showing we end up on the 20th floor.
If we go down 5 floors, then we write 15-5 = 10
Adding makes us go up, subtracting makes us go down.
If we add on a positive number, then we go up, but adding on a negative number ultimately has us go downward.
This is because of something like 15 + (-5) = 15 - 5 = 10.
Subtracting a negative is really the same as adding. Subtracting pulls us down, but the negative counterbalances things to go the opposite direction (going up). So that's why 15-(-5) = 15+5 = 20.
--------------
Yet another way to look at it:
Negative values are useful in finance when talking about debt.
If you have 5 iou's of debt, then we write this as -5
If you transfer that debt to a friend whos account balance is $15, then their balance becomes 15 + (-5) = 10 dollars. They would have 10 dollars left after paying the debt.
Now let's say the friend got those iou's taken away and someone else paid for them. That would mean we would say 15 - (-5) = 15+5 = 20 is that first friend's new balance. Effectively they got 5 additional dollars when that debt was taken off their hands.

Boskyville is planting tree along both sides of its streets.The trees will be planted 50 feet apart. the first tree on the block must stand 20 feet from the corner. if the blocks in boskyville are 390 feet long, how many trees will be planted along one block?
A.14 trees
B. 16 trees
C. 8 trees
D. 7 trees
Answer:
7 trees will be planted along one block.
Therefore, option D is the correct choice.
Step-by-step explanation:
The length of the block in boskyville = 390 feet
The condition is that the first tree on the block must stand 20 feet from the corner.So subtract 20 feet from the length of the block in boskyville.
i.e 390 feet - 20 feet = 370 feet
Given the trees will be planted 50 feet apart.Thus, divide the 370 feet by 50 feet would bring us the total number of trees being planted along one block
i.e.
Trees along one block = 370 / 50
= 7 (Rounded to the whole number)
Thus, 7 trees will be planted along one block.
Therefore, option D is the correct choice.
James earns $2.20 less than twice gregs hourly wage. If james earns $16.50 per
hour, what is gregs hourly wage ?
Answer:
James earns $2.20 less than twice Greg's hourly wage. If. James earns $16.50 per hour, what is Greg's hourly wage? let x= Grea's hourly wage. 2x-2.20-James' hourly wage. 2x-2.20=16.50. 2x=16.50+2.20. 2x= 18.70.
If James earns $2.20 less than twice gregs hourly wage.If james earns $16.50 per hour, then gregs hourly wage is $9.35
What is equation?Two or more expressions with an equal symbol operator is called equation.
Given that james earns $16.50 per hour,
and James earns $2.20 less than twice gregs hourly wage.
let x= Grea's hourly wage.
James earns $2.20 less than twice gregs hourly wage by data.
2x-2.20=James' hourly wage.
2x-2.20=16.50.
2x=16.50+2.20.
2x= 18.70.
Divide by 2 on both sides
x=9.35
Hence gregs hourly wage is $9.35.
